So far, we don't have much data to go on to observe the impact of COVID19 on our local market.

Watch this if you want to see a graphic and explanation of why it's not overkillAlso, in our area of Redding, CA (and most of CA) there are no test kits to speak of, and many more have the virus than is being reported, and more deaths than we know, as without being tested they cannot report the death as being from the virus.

The 2nd assumption is based on fear and has little analytical data to back it up.

I don't know what an 'appraiser website' is, or where they get their data.

My area is lax on lead issues (provide a pamphlet and have them sign a disclosure) while MD is strict (registration, testing, certifications, etc.), so figure out what issues will cause the most headaches in your area.  

Also helpful Test kits, PPE for health care, & Ventilators become available.Finding good numbers/data for this was really tough with how quickly things are changing.

Usually, only heating oil USTs associated with commercial properties are regulated. thus, most home heating oil tanks may and often are taken out of service without any oversight from state regulators.Second- the rules that are in effect for heating oil tanks are usually less stringent than for diesel or gasoline tanks since heating oil tends to thicker and may not migrate as far. as a result, many states just require tanks to be cleaned out. they may also require the tanks to be filled with sand or concrete to prevent collapse. but sampling may not be required.Third- the key to determining if a tank has leaked is to collect soil samples from around and beneath the tank (groundwater also if groundwater is shallow). another quick way to see if a tank is leaking is to "dip" it with a stick that has a paste that turns color in the presence of water. generally, if water has gotten into a tank, it can mean oil has leaked out of the tank (although a certain amount of condensation may be present even where there is no leak so this is not a infallible test).Fourth- if there is currently a tank in the basement, ask the owner if there used to be a buried tank (a/k/a underground storage tank).Fifth, If the tank has impacted the soil, the cleanup generally varies from $25K to $50K though the costs will depend ont he depth of the contamination. i once had a home with a heated pool that had pressurized piping and used diesel. the contamination went down 40 feet and the consultant went crazy excavating the soil to the tune of $400K!!!

4o years of data with multiple recessions will tell you that Austin will do just fine. 

I would also recommend you read on the mentioned testing so you can make a decision on whether it is even warranted based on the location and characteristics of the property.

Make sure the property cashflows when you buy it; make sure you stress test the deal.
